Speed of managed programs

I found this: Microbenchmarking C++, C#, and Java

Maybe the managed code has a future in game development. I think so.

I've found a lot of argument in forums about C++ vs C# or C++ vs Java. It's hard to decide which one is better. I just love managed stuff. If C# and XNA make 90% of the speed of C++ and DirectX, that's enough because my goal is writing a cool-looking game and not Doom4. :)
